介子

Also ,, and constitute the first radial scalar meson nonet, it is supposed that these states would likely correspond to the observed states ,, and ,respectively. The scalar state may be a good candidate for the ground scalar glueball.

结果表明，和组成基态标量介子九重态，它们分别对应于实验上观测到的共振态，，和；，，和组成第一径向激发标量介子九重态，它们分别对应于实验上观测到的，，和共振态；而是基态标量胶球很好的候选者。

Ideally, they would use muons but, in practice, they are using a close cousin, the pion.

选用μ介子是最理想的，但在实验中使用的是与之很相似的介子。

Our results are matched to the known soft pion limit.

作为补充，在软的轻介子区域，我们将所得结果与重介子手征微扰论的结果进行了拟合。

We also discuss the contributions of the form factors and from different parts of the pion, the kaon and the B meson wave functions.

我们还讨论了π、K介子和B介子波函数的各个不同组成部分对形状因子的贡献。

We find the electromagnetic effects play the dominant role for both the pion and rho meson mass splittings.

我们发现无论是对于π介子还是ρ介子的质量分裂，电磁效应都占主导地位。

The possibilities for experimental study of meson production at Cooling Storage Ring of Lanzhou are discussed. It is shown that the study of production of the pion and eta mesons at CSR is of significance.

讨论了在兰州重离子加速装置冷却储存环上开展介子产生的实验研究的可能性和进行π和介子产生研究的意义。

The IQMD model is introduced in detail at first, then shows the production machanism of pions and the generation machanism of concave pion spectra at length.

首先，对 IQMD模型做了介绍，讨论了模型中π介子的产生机制及π介子谱的双玻尔兹曼分布的形成机制。

The reasons of our choice are:(1) the coupling of the electromagnetic field with the matter is universal and there is already some experiences with such a kind of field in the literature;(2) the pion is the lightest hadron and its interaction with other fields are known to some extent. The pion fields have been treated as external fields but the discussion is not comprehensive in the literature.

我们选取这样的外场的理由如下：(1)电磁场与物质相互作用的耦合常数是普适的，而且文献中已经有把电磁场当作外场来处理的经验；(2)π介子是最轻的强子，它与其它场的相互作用人们已经有所了解，文献中也有把π介子场当作外场来处理的例子，但讨论还不够深入。

Finally, the problem in decays of heavy mesons into light pseudoscalar mesons isanalysed.

最后，分析了重介子衰变到轻赝标介子过程中的问题。

Ii The form factors of heavy pseudoscalar meson decays to light vector mesons are systematically analyzed, in a model independent way.

对重赝标量介子到轻矢量介子跃迁的形状因子作不依赖于模型的分析，给出了1/m〓阶的所有独立的普适函数的数目。
